Duluth, Minnesota

I’m not entirely sure the reason, but we’ve definitely been pulling in a lot of Minnesota forecasts lately. One would hope that this homefield advantage does us some favors, though.

At 802PM, CT, Duluth was reporting a temperature of 35 degrees with light snow. The airport lies uphill and away from Lake Superior, so the downtown area, and Superior across the border in Wisconsin were reporting rain. Snow was more vigorous in Arrowhead, and accompanied by strong winds coming off of the Lake. A broad trough lies over the northern US, and there is an embedded shorter wave over the upper Midwest, leading to a surface wave centered over Wisconsin, with the back end bringing the wet weather to the North Shore.
The short wave will merge into the broad trough, and the low over Wisconsin will spiral back into a broader surface low arriving from the Dakotas. Lingering rain and snow showers will continue through most of the day tomorrow, particularly north of Duluth, before the larger system moves into northern Minnesota by tomorrow evening. Tuesday will be a wet day, with some rain, but snow as well, particularly in the afternoon and evening, as cold air pivots into the region. Up to 2″ are possible.

Temperatures are pretty borderline, but the fact that some snow has already fallen, and more cold air is going to fill in aloft, I fell comfortable putting snow in the forecast. Here is the radar with snow across Lake Superior.
